last year my son (who was 3) couldn't make up his mind until mid october. I had already had his Nana making him a super cool cars cape and he ended up going as a frog (that I bought 2 days before halloween).

This year he is 4 and I had him talking about it months ago. He has decided to be Woody and his Nana is making his costume again (god bless her!) and I ordered a Jessie inspired dress for my 18 month old to match him. There will be no mind changing this year.
